SL 486YB INTRODUCTION! This manual has been designed for several purposes. If the SL 486VE is already set up in a functioning system, it will be helpful to reviewthe manual to become familiar with the features of the board and where things are. This will be helpful in the unlikely event there is a problem with the system. For those who want to alter the board's configuration or upgrade it, the manual will serve as a guide to both procedures and specifications. While the necessary information is included in the manual, we recommend that unless you feel confident of your ability to do the work, it would be best to have your dealer or a local service shop do it. Before making alterations to the system, check to see that doing so will not violate the system warranty. If it does, have the work done by an authorized dealer. The "chip set"consists of six chips; SiS85C411/420/431/405/406, which incorporate most of the logic required for a low-cost, highly integrated IBM PC AT-compatible computer. IMPORTANT: The chip set requires correct configuration information; otherwise a malfunction may result. CAUTION: Static electricity can cause serious damage to integrated circuit chips. To avoid building up a static electric charge on your body, touch a grounded object before touching the chips and at frequent intervals as you handle the chips. If chips are handed from one person to another, the two should touch hands first, then pass the chips. i Information presented in this publication has been carefully checked for reliability; however, no responsibility is assumed for inaccuracies.

(Please refer to Figure 3.1) The major components and their basic features and functions are outlined as below: • 8 0 4 8 6 CPU (Central Processing Unit) The central processing unit is the brain of a computer system that interprets and executes instructions, such as performing calculations, routing information, and temporarily storing data. In personal computers, the CPU is a highly integrated chip called the microprocessor. 11 SiS/EISA 4 8 6 Chipset The SiS85C405, 85C406 , 85 C411, 85C420, and 85C431 chipset supports 486-based EISA system. Such chipset is achieved through a very high level of function integration, system partition and is proven to be a highe performance, compact and cost-effective product. This EISA chipset consists of the following: П SiS85C405 (Address Buffer) The Address Buffer is a buffer interfacing between EISA LA and SA address bus. It also contains EISA bus refresh counter to generate address during refresh cycle. n SiS85C406 (Highly Integrated System Peripheral) The Highly Integrated System Perpheral integrates all the necessary peripheral control logic used in eisa specific applications, the SiS85C406 4-2 Introduction consists of: an arbitration scheme that allows efficient bus sharing among multiple EISA masters, the host CPU, Refresh, and DMA devices; a seven-channel programmable DMA Controller, a 16 level programmable interrupt controller which provides level or edge triggered interrupt capability on a channel-by-chaneel basis; non-maskable interrupt logic for multiple NMI control and generatin; five counters/timers which provide a system timer interrupt, DRAM refresh requests, a fail safe timer, a speaker tone output, and a periodic CPU speed control. Besides, SiS85C406 also integrates the imperative glue logic in EISA system to further minimize the number of board components. П SiS85C411 (System/Cache/DRAM Controller) The System/Cache/DRAM Controller provides powerful cache, DRAM and CPU interfaces utilizing the integration of faster and configurable memory functions and most efficient cache systems. Its memory logic circuit can respond to the CPU and EISA burst cycle allowign faster transfer operations. With its bank (or double-word) memory interleaving, systems at full speed can attain the utmost memory speed. a SiS85C420 (EISA Bus Controller) The EISA Bus Controller is a generic EISA Bus Controller which contains all the necessary logic to control EISA bus cycles in the system level design. The SiS85C420 provides the state machines that interfaces to the host, EISA, and ISA buses, and is loosely coupled with SiS85C411 to support 8-, 16-, and 32-bit masters and slaves. SiS85C420, combining with SiS85C406, creates a full feature of EISA system board. n SiS85C431 (EISA Data Buffer) The EISA Data Buffer is a general data path chip that provides all the data routing and swapping between the host data bus, memory data bus, and EISA data bus. It also contains parity genertion and detection logic. • Real-Time Clock The Real-Time Clock contains a self-contained lithium battery which offers ten years of data retention capability. 1-3 SL 486VE User's • Manual Real-Time Clock The Real-Time Clock contains a self-contained lithium battery which offers ten years of data retention capability. • Non-Volatile SRAM The NVM employs 4K x 4 of SRAM and a self-contained lithium battery which offers ten years of data retention. The NVM can keep the EISA system and add-on card configuration information. A BIOS In addition to reducing space and cost, it allows the user to enable the BIOS shadow feature for access to the fast chip (DRAM) instead of the slow one (EPROM). • Jumpers On the SL 486VE there are several jumpers which should be properly set according to the system configuration. Detailed information regarding all jumpers can be obtained from Chapter 3. • Connectors Several connectors are used to connect the power supply, keyboard and LED indicators. Refer to Chapter 3 for more details. • Slots Eight EISA 32-bit slots with 6 EISA-master slots (S1-S6) and 2 EISA- slave slots (S1,S2 Two VESA slots (S9, S10) with one master/ one slave slot or two slave slots. 4-4 Memory Configuration Chapter 2 Memory Configuration In this chapter, the SL 486VE DRAM configurations are discussed, followed by instructions for DRAM module installation and removal. Users are recommended to read through this chapter before installing or removing memory. 2.1 System Memory The SL 486VE provides tremendous flexibility to support a number of different on-board DRAM configurations. The on-board DRAM is installed with SIMM (Single-In-Line Memory Module). There are two banks of DRAM module slots seated on the SL 486VE to support up to 128 MB of on-board memory. The location and layout of all the SIMM banks is illustrated below and shown in Figure 3.1: BANK 0 BANK 1 SIMM M EIV О RY Each bank is composed of four standard 30-pin SIMM sockets. These sockets take 256KB, 1MB, 4MB, 16MB SIMM. 2-1 SL 486VE User's Manual Note that all of the four SIMMs within a bank must be of the same type; you can not mix 256KB, 1MB, 4MB, or 16MB modules in the same bank. The SL 486VE board provides 8 sockets for SIMM modules. These 8 sockets are divided into two banks and each bank can accommodate four SIMM sockets. Every bank can accept 256KB, 1MB, ,4MB or 16MB SIMM modules, but all of the four SIMM modules used in the same bank must be the same size. This ability for mixing assorted SIMM modules on the two banks allows the system to be shipped with minimal memory and upgrade without sacrificing the memory already on board. Since this main board is designed to automatically scan the total memory installed, there is no jumper for further adjustment when installing or reinstalling the SIMM modules. Please note that there is a bank ordering restriction for SIMM installation. In other words, the user must install SIMM modules from left side (bank 0). 2.1.1 DRAM Module Insertion The SIMMs must be seated on the sockets as firmly as possible, and, because of the fragility of the slot, you must be careful when inserting or removing the module. 1. Align the module so that the pin-1 marking and corner notch of the module correspond to the SIMM socket pin 1 marking at the rear of the board. The module can fit in the socket one way only. Do not force it! 2. Push the module against the clip arms with your thumbs until a "clicking" sound is heard; the little plastic tabs appear in the latching holes on the RAM module board, and the clip arms fully grab the module board. 4-2 Memory 2.1.2 Configuration DRAM Module Removal If possible, use a SIMM extraction tool; otherwise use the following method: 1. Carefully use your thumbs to bend outward the plastic tab ends on both sides of the slot. 2. The RAM module board will be automatically ejected off the clip arms. 3. Take it out of the socket. 4. Repeat step 1 through 3 to release the other RAM modules. 2.2 Cache Memory Subsystem For CPU cycles, the content of the cache memory is renewed when either the cache read miss or write hit occurs. Tag and data RAMs are both updated in the cache read miss cycles. In the cache write hit cycles, the SiS85C411 updates only the data RAM. In the cache write miss cycles, the 80486 writes data into the mam memory (DRAM), while the cache memory remains unchanged. The alter bits in the write-back cache are reset in the cache update (read miss) cycles and set in the hit cycles. When the cache is disabled, all the CPU reads to the cacheable memory are treated as cache read miss, so both tag and data RAMs are updated. This feature is used to initialize the cache memory before enabling it. In DMA/master cycles, the cache data RAM is written when a writen when hit occurs, to assure the cache coherency. Cache memory is not accessed in DMA/master write miss or read cycles for write-through cache. For the write-back cache, DMA/master read hit cycles are conducted to the cache, not to the DRAM. The following is the Cache size options. Cache Size Tag RAM Data RAM Dirty Bit Cacheable Size 6 4 KB 16K x 4 x 2 8K x 8 x 8 16K x 4 x 1 16 MB 128 KB 16K x 4 x 2 32K x 8 x 4 16K x 4 x 1 3 2 MB 2 5 6 KB 16K x 4 x 2 32Kx 8 x 8 16K x 4 x 1 6 4 MB Note:The 128 KB Cache memory are installed by 4 pieces of 32K x 8 bit SRAM on U30, U31, U32, U33. 2-3 SL486VE User's Manual The on-board DRAM beyond the cacheable size is not cacheable for the secondary cache. It is still cacheable for the 80486 internal cache, however. To reduce the propagation delay of the chip output buffer, the SiS85C411 employs an "advanced clock" instead of CPU clock to clock the cache read control signals. The advanced clock should lead CPU clock by 3 to 7 ns. It will increase the margin of data RAM access time. For 16/20 MHz systems, the ACLK can be connected to CPUCLK to simplify the clock circuit. The following is a table of cache configurations and suggested speed ratings of the SRAM for implementing the cache data RAM for various speeds of the 80486 CPU. Cache Configuraion 2-1-2 Interleave * 25 MHz CPU 33 MHz CPU 50 MHz CPU None 20 ns 20 ns 2-1-2 Non-interleave 20 ns None None 2-2-2 Non-interleave 20 ns 20 ns None 3-2-3 Non-interleave 20 ns 20 ns 20 ns ns 20 ns 3-2-3 Interleave 20 ns 20 N o t e : " * " x -y- z means x-y-y-y burst read and zT write cycle. Interleave means two banks Cache (64KB/256KB) Non-interleave means one bank Cache (128 KB).

If the information it retrieves is incorrect or insufficient, the system may not be able to operate properly until accurate information is supplied. You do this by means of the SETUP program built in the system BIOS. 4.2.1 When Should You Run Setup ? 1. Although someone may have set up the system for you,you may want to adjust the system to fit your needs. 2. Whenever you change some components in your system, (for example, if you add a hard disk or more memory), you must run Setup to record the new system configuration. If you don't do so after adding memory, the computer will prompt you to run Setup. 3. The last and most unlikely possibility is the loss of information in the CMOS memory. You may never encounter this situation. But if you do, you can restore the information by running the Setup. 4.2.2 How to Recall the Setup Program ? You can run the built-in SETUP program in several ways: 1. When powering-on the system When you turn on the system power or press the reset button on the system case while the system is running (not every system has this button), the BIOS will first test the functionality of the system components and display a start-up message similar to the following: XXXX KB OK Hit <Del>,If you want to run Setup The numeral digits will continue to count at the top left of the screen. This represents the BIOS testing the mainboard memory chips. Before the above message disappears, you can press the < D e l > key to run the Setup program. 2. To reset the system By pressing < C t r l > < Alt > < D e l > key combination when the system is up and running (assuming you are running under DOS or other environments that support this feature), the system will immediately reset itself and boot up. Before booting up from a diskette or hard disk, you can also see the below start-up message : Hit <Del>,if you want to run Setup 4-2 Built-in BIOS Setup Program Chapter 4 Built-in BIOS Setup Program This chapter provides detailed instructions on how to configure your system using the Built-in BIOS Setup program and gives some technical information about your computer. If you are not very familiar with microcomputers, please read this chapter carefully before proceeding. If you do not want to change the system's configuration, you can skip this chapter. Before you start to add optional devices to your system, you should first learn how to set up your system and adjust its jumpers (Refer to Chapter 3 for detailed information). You may run the Setup program of the SL 486VE only after all jumper setting adjustments have been completed. At this time you should record what the configuration is, and keep it for reference. 4.1 Setup Summary 1. 2. 3. 4. 5. 6. 7. Install any extra memory SIMMs. Set jumper JP14 for color or monochrome monitor. Make all connections to board. Install control cards, monitor, and any peripheral devices and drivers. Turn on system. At setup prompt, press the Del key. Type the password if you set the password checking option to "Setup" or "Always" in the Advanced CMOS Setup program. 8. Choose Standard CMOS, Advanced CMOS or Advanced Chipset Setup. 9. Follow screen prompts. 4 . 2 BIOS Setup Every AT-compatible computer has battery supported CMOS memory otherwise called "non-volatile "RAM. It stores information about your computer and peripheral device configuration. Unlike ordinary RAM, it retains the information even after you turn off your computer. A computer needs to know certain things about itself so it can operate correctly when powered on. A special type of software called BIOS (Basic Input Output System) is contained in read-only memory (ROM) chips on the mainboard. The BIOS reads information from the CMOSmemory every time you power on the computer. It then instructs the CPU and other devices 4-1 Built-in BIOS Setup Program 3. When the BIOS prompts you In the self-test process, if the BIOS detects inconsistent or incorrect configuration information or some physical system error, it will display an error message on the screen, and prompt you to take action; for example: Run SETUP UTILITY Press <F1> to RESUME Press the < F 1 > key,and continue. 4. 4.2.3 To Enter password If you set the password checking option to the "Setup" or "Always" field in the Advanced CMOS Setup program, after pressing the "Del" key to run the Setup program, the Enter password message will be displayed on the screen. Refer to section 4.6, Using the Change Password Setup. Running the SETUP Program When you call up the Setup program, the screen displays a "main menu" similar to the following: BIOS SETUP PROGRAM - AMI BIOS SETUP UTILITIES (C) 1991 American Megatrends Inc., All Rights Reserved STANDARD CMOS SETUP ADVANCED CMOS SETUP ADVANCED CHIPSET SETUP AUTO CONFIGURATION WITH BIOS DEFAULTS CHANGE PASSWORD WRITE TO CMOS AND EXIT DO NOT WRITE TO CMOS AND EXIT Standard CMOS Setup for Changing Time, Date, Hard Disk Type, etc. ESC:EXIT 4- — : S e l F2/F3:Color F10:Save&Exit Figure 4.1 BIOS Setup Main Menu Options On-screen instructions at the bottom of the screen explain how to use the program. 4-3 SL 486VE User's Manual The following is a brief description of the six options of the Setup main menu: • STANDARD CMOS SETUP Display the standard CMOS Setup screen to check or modify general configuration information.

H System Boot Up Num Lock This option can set the "Num Lock" key to "On" or " O f f ' a f t e r system boot up. H External/ Internal Cache Memory Due to constraint of technology, speed of currently available D R A M may not be high enough to catch up with the speed of the CPU, which means that at every step of program execution, the CPU must wait for the DRAM to respond. In fact, for CPU to run faster, the system must be designed to use another kind of fast RAM chip — S R A M (Static-column RAM). You can have a dual cache architecture - internal (from the CPU) & external cache (from the SRAM). И Password Checking Option The purpose of this field is to determine whether the password is asked for in every boot (set to "Always") when entering into the Setup program (set to "Setup") or never asked for (set to "Disabled"). • Video ROM Shadow Choose these two options for better video display performance.

DMA Speed . DRAM Write CAS Pulse Width • Cache Write Cycle • Cache Burst Read Cycle • BUSCLK Selection If disabled, user selected values for above parameters will be used. The available options are listed below: • • Disabled Enabled 4-9 SL 486VE User's Manual • DRAM Speed There will be plenty of timing marging if the user adopts Fastest for 25 MHz, Faster for 33 MHz, and Slowest for 50 MHz, even when 100ns D R A M s are used. If 70/ 80ns DRAMs are used, faster speed option can be selected. • DRAM Write CAS Pulse Width The option determines the number of wait states to be kept when the CPU writes data into the local DRAM. The available options are as follows: . 2 T . IT Ш Cache Write Back I f disabled, cache is write-through. If enabled, cache is write-back. A writeback cache can offer higher performance than a write-through if writes to the main memory are much slower than writes to the cache. The write-back cache is also favored when a memory location is written several times in the cache before written into the main memory. The performance advantage of the write-back cache over write-through cache is software dependent. • Cache Write Cycle During CPU cycle, it is used as a write latch function to support longer data hold time for DRAM write, while in hold acknowledge cycle it indicates cache read hit. • Cache Burst Read Cycle Due to constraint for technology, speed of currently available SRAM may not be high enough to catch up with the speed o f t h e CPU, which means that at every step of program execution, the CPU must wait for the SRAM to respond. This option determines the number of cycle times to be inserted when CPU read data to SRAM. Moreover, the setting depends on the speed of the CPU and SRAM. I f the CPU is of high speed, the timing of SRAM processing data needs an extension, except for some SRAMs that can be high enough to catch up with the speed of CPU . The available options are as follows: « 2-1-1-1 . 3-1-1-1 о 3-2-2-2 4-10 Built-in BIOS Setup Program • BUSCLK Selection The BUSCLK Selection is an output clock for the I/O channel. This field used to specify the I/OBUSCLK clcok source used by the system. The user does not need to change this settings. The available options are listed below: . 7.159MHz . CPUCLK/2 (is • CPUCLK/2.5 . CPUCLK/3 (is . CPUCLK/4 (is . CPUCLK/5 • CPUCLK/6 (is . CPUCLK/8 • recommended for 16 & 20 MHz) recommended for 25 MHz) recommended for 22 MHz) recommended for 50 MHz) Non-Cacheable Area 1/2 In some applications, users desire a block of memory not to be cached. The mainboard provids two programmable non-cacheable regions to serve this function. The memory residing on the AT add-on is non-cacheable. When a memory space is mapped by both the on-board DRAM and AT add-on memory, CPU access will be conducted to the on-board D R A M . If users desire the AT add-on memory to be accessed instead of the on-board D R A M at the overlapped memory space, the two non-cacheable regions can be used to disable the on-board DRAM in the proagrammed space. H Non-Cacheable Area 1/2 Size For some special I/O cards which need to use system memory, you should reserve some memory space for use. The size of the Non-Cacheable Area 1/2 can be as small as 64KB or as large as 4MB. The Non-Cacheable Area 1/2 Start is set to be "Disabled" as default value. • Non-Cacheable Area 1/2 Start This function is to set the address of Non-Cacheable Area 1/2 from starting. • C000 Shadow RAM Cacheable If you have a shadowing of the video BIOS at C000 Shadow RAM, you can enable this memory cacheable. • FOOO Shadow RAM Cacheable If you have a shadowing of the system BIOS, you can enable this option for memory cacheable function. 4-11 SL 486VE User's Manual Я DRAM Hidden Refresh Recently the speed of DRAM is becoming faster so the time needed per refresh cycle is getting shorter. The refresh cycle time for the 100ns DRAM is 200ns minimum, for example. In a system with cache, most of the CPU accesses are referred to the cache so that the DRAM usage (percent of time the D R A M is accessed by the CPU) is significantly reduced. В I/O Recovery Select This field is used to specify the I/O command recovery time except for some add-on card that cannot work properly. It is recommended to set this option at low" value to enhance the I/O performance. The available options are as follows: о . . . 3 BCLKs 4BCLKs 5BCLKs 11 BCLKs 4.6 Using the Change Password Setup To change the password.choose the "ГН ANOF PASSWORD"option from the Setup main menu and press < Enter > . 1.

EISA systems and adapter cards are much more complex and flexible than the older ISA designs. The EISA configuration Utility was created to automate this configuration process in EISA systems. The E C U permits the user to configure an EISA computer. The E C U takes into account the needs of all adapter cards in the system. The E C U configures the EISA devices and sets and maintains system parameters, storing them in EISA CMOS R A M . The ECU guarantees that there will be no conflicts or contention issues between adapter cards, since it assigns all necessary system resources. The E C U must be executed every time ISA or EISA adapter cards are physically added, removed, or moved. The E C U operates on the information provided by the CFG (configuration) files that accompany the EISA motherboard and EISA or ISA adapter cards. 5.1 EISA Specification EISA is an acronym for Extended Industry Standard Architecture. EISA is basically a superset of the Industry Standard Architecture (ISA), which is based on IBM's original PC/AT specifications. The EISA specifications allow 32-bit memory addressing to be used by the CPU, D M A devices, and bus mastering devices. The above devices can also use either 16-bit or 32-bit data transferring. 5.1.1 EISA/ISA Differences An important different between ISA and EISA is that in EISA systems, configuration is done through software, rather than the hardware switches 5-1 SL 486VE User's Manual used by an ISA system. In other words, I/O ports, R O M addresses, memory use, and the IRQ and DMA lines for an EISA motherboard and adapter card are configured using an E C U , where an ISA card uses DIP switches and jumpers to perform the same function. 5.1.2 EISA Bus Specification The EISA computer has 32-bit expansion slots that are fully compatible with 8-bit and 16-bit PC/XT/AT expansion slots. EISA expansion slots have 188 pins. The upper 98 pins are exactly the same as the standard AT pinouts. The lower 90 pins are used for EISA bus signals. The EISA bus is much faster than the ISA Bus. Not only does EISA provide a wider 32-bit bus, it also provides a maximum 33 MB/sec bus transfer rate. An ISA bus can transfer data at only 8 MB/sec. EISA achieves this higher throughput using high-speed burst mode transfers, which take only one clock cycle. Normal (ISA compatible) transfers take two clock cycles. EISA Bus Rate Versus the ISA Bus Rate Attribute EISA Bus ISA Bus Burst Transfer Rate 33 MB/sec 8 MB/sec at 0 wait states DMA characteristics Supports 8, 16, and 32-bit DMA Supports 8 and 16-bit DMA DMA Transfer Rate 33 MB/ sec 1 to 4 MB/seo Adapter Card Pin Count 188 pins 98 pins Bus Master Intelligent Bus Master No Bus master Configuring Adapter Cards Auto configuration through ECU. DIP svutch and j u m p e r setting still available. Only DIP Switch and jumper setting available. 5.1.3 EISA Configuration Utility Features A practical benefit of EISA is automatic configuration of system resources and adapter cards. That means an end to DIP switches, jumpers, and 4-2 EISA Configuration Utility installing configuration files, although switch configurations are still allowed for both ISA and EISA to maintain compatibility. EISA provides a product identification mechanism for system and adapter cards. The computer automatically interrupts each device during the BIOS Power-On Self Test (POST) for the product identifier, compares it with the ID stored in EISA Extended CMOS RAM and configures the adapter card accordingly. The EISA configuration scheme has the following characteristics: • An ECU (EISA Configuration Utility) for configuration of motherboards and adapter cards. • A software interface to the ECU used by CFG files to control the configuration process. . CFG files for the ECU. • CFG files for the motherboard and adapter cards. • EISA Extended CMOS RAM to store configuration parameters. ® A mechanism to save and restore the configuration parameters. о BIOS routines to read and write to Extended CMOS RAM. о Automatic detection and initialization of adapter cards by the BIOS during POST routines. • 1 KB of I/O address space for each EISA expansion device (adapter card). 5.2 Configuring Your Computer for the First Time The first time you set up your EISA computer and any time you change the configuration by adding or removing an EISA or ISA board, you must configure your system with the EISA Configuration Utility program. When the configuration process is completed, the configuration is stored in the computer's nonvolatile memory where it is available to the system whenever you use your computer. The EISA Configuration Utility program is on the System Configuration diskette provided with your computer. Before you use this diskette to run the Configuration Utilityprogram,we recommend that you make a backup copy. This ensures that you will be able to run the program if the original diskette is damaged or lost. 5-3 SL 486VE 5.3 User's Manual Installing the ECU The E C U is easy to install and can be used from either a hard disk drive or a floppy drive. Hard Disk Drive Operation Simply copy all files from the ECU floppy disk to the same directory on the hard disk drive. Make sure all CFG files are copied to the same directory. Floppy Drive You can execute the ECU from a floppy drive. Make a backup copy of the AMI E C U floppy disk to use as a working copy. You may have to run the ECU from a floppy drive if the system hard disk drive must be configured by the ECU before it can be used. System Requirements The following are the minimum hardware and software requirements necessary to successfully use the E C U : • . • MS-DOS Version 3.2 or later 640 KB of R A M Memory 1.2 MB Floppy disk Drive and a hard disk drive, monitor and keyboard. EISA Configuration Files The E C U floppy disk should contain the following files: . CFG .EXE the ECU (EISA Configuration Utility) . EISACFG.HLP E C U Help file • Several CFG files for ECS products. Additional file can be created as the ECU is executed. • о 4-4 the CFG .ISA file is created when any ISA adapter card is configured .CMS files are created in the EISA configuration process, as are .INF files. EISA Configuration Utility CFG Files Each adapter card in the EISA system should come with a CFG file on floppy disk. A card's CFG file contains detailed information on the card as well as the functions that the card can perform. The CFG file tells the E C U the possible configuration choices for the adapter card and the system resources that the adapter card needs. System resources include BMA(Direct Memory Access) channels,IRQ (Interrupt Request) lines, I/O Address Ports, and m e m o r y s p a c e . B e s u r e a l l C F G files for all cards in the system and the CFG file for the motherboard are available before running the E C U . CMS File The CMS file contains a copy of the configuration information that is written into the system's Extended CMOS Memory. The default name for a CMS file matches the ID of the system board that was used in the configuration. Each CMS file should have a corresponding INF file. SNF File The INF file contains detailed information about a configuration such as switch and jumper settings, software statements, connection statements, and resource allocation. The INF file is used by the "Display/Print" command to recall information on a saved configuration. Each INF file should have a corresponding CMS file. Pi Running the EISA Configuration Utility The E C U operates on the information provided by the CFG (Configuration) files that accompany the EISA mainboard and EISA or ISA adapter cards. The E C U stores configuration data in a battery-backed EISA Extended CMOS R A M . When an EISA system is powered on, the BIOS reads this configuration information and initializes all adapter cards in the system. If the battery runs down, the contents of CMOS R A M can be lost. You must then either reconfigure the system or copy the configuration data to EISA Extended CMOS R A M from a backup source. 5-5 SL 486VE User's Manual 5.4.1 Main Menu The main menu outlines the six steps involved in configuringan EISA system.
